What do you do after you have created one of the most iconic multi-label fashion stores in history? For Sarah Andelman, the co-founder of Colette, her second act is all about making creative and unexpected connections between brands. Her one-woman consulting agency, which she perfectly baptized Just An Idea, is a natural extension of her character. The concepts and collaborations the agency facilitates are all upbeat, original, and have just the right amount of joyful pop. Here, Andelman discusses what she sees for the future of luxury retail, how her life has changed post-Colette, and why she always wears skirts.
